VMJVE FOR INTERNAL-COMBUSTION ENGINES;

Application filed July 18, 1917. Serial No. 186,407.

To all whom it'mcg concern.

Be it known that l, WARRENJAMES Gno- NINGER, a citizen of the UnitedStates, residing at Port Royal, in the county of il uniota and State ofPennsylvania, have invented a new" and useful Valve forllnternnl-Combustion Engines, of which the following is a specification.

The device forming the subject matter of this application isan internalcombustion engine, and one object of the invention is to provide novelmeans whereby the valves of the engine may. be taken apart readily, tofacilitate cleaning or repair, and to give access to thespace betweenthe cylinder heed and the piston.

- Another object of the invention is to provide an engine of the typeabove mentioned, having valves with which there will be no troublecaused by carbon deposits on the valves, a condition frequently arisingwhen beveled valves fit on a beveled seat.

Another object of the invention is to im prove the valve construction byreducing to the greatest possible extent, the wear on the valves.

It is within the province of the disclosure to improve generallyand toenhance the utility of devices of that type to which the presentinvention nppertsins.

With the above and other objects in View Which will appear as thedescription proceeds, the invention resides in the combination andarrangement of ports and in the details of construction hereinafterdescribed and claimed, it being understood on changes in the preciseembodiment of the invention herein disclosed can be made within thescope of What is'clnimed, Without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 tcrnal combustion engineconstructed in accordance with the present invention, parts appearing insection;

Fig. 2 is a section taken approximately on the line 2-2 of Fig. 1;

Fig. 3 is astop plan of the engine, parts being broken away Fig. 4: is acomposite perspective wherein portions of the valve mechanism are shownin spaced-relation.

shows in side elevdtion, an in Patented Nov. 2'7, lltlill tionmechanisms, are provided. The forego- 111g are common engine detailswhich may be passed over briefly.

The cylinders 2 are provided at one side with a horizontal shoulder 9and above the shoulder 9, the cylinders are supplied with lateralopenings 10 communicating with the space between the pistons? and theheads of the cylinders. Supported on the shoulder 9 and shutting againstthe side of the cylinders is a gasket 11 having ports 12 communicatingwith the openings 10 in the cylinders Supported on the shoulder 9 andabutting against the gasket 11 is a carr'ier or block let, held in placeby bolts 15 or other securing elements, engaging the carrier or blockand erlgngin the cylinders 2. lf desired, cover plate 16 may be sooureddetnchnbly to the block or carrier 1 and to the upper portion of thecrank case 1, for the purpose of housing and protecting certain oi themovable parts of the device. The cover plate 16 is :1 useful but notmundatory element. J

The carrier is provided With bores 17 the axes of which are parallel tothe axes of the cylinders 2. The carrier 14 includes base 18. Thecarrier 14 supplied with inner ports 19 coinciding with the ports 1:2 ofthe gasket 11 and communicating with the cylinders 2 by way of thelateral openings 10 in the cylinders. The carrier M is provided withouter ports disposed diametrically opposite to the ports 15 A sleeve 2-2of cylindrical form is dis posed in each. bore 17 and is supported onthe hose 18 of the carrier ll. The sleeve 23 has an inner portcoinciding: With one of the ports 19 in the carrier 14, and has, also.an outer port 2 coincidingwith one of the ports 20 of the carrier lfl.The ports 23 'end inthe sleeve 2-2 are disposed. diametrically oppositeto each other. The

- sleeve "92 is held in the bore 17 by means of a cap 25, of cup-shapethe cap being threaded into the upper end of the bore 17. If desired, asindicated in Fig. 3, the inner surface of the wall of the cap 25 may befluted .at 26, to facilitate a rotation of the cap, The cap 25 beers onthe upper end of the sleeve 22 and binds the some on the been llltlMilli 18 of the carrier 14:. The cup 25 may carry on oil cup 92'. v 4

'lVlcunied to reciprocate in each. sleeve 22 is o. valve 28 oi? thepiston type, tl'ie'saine having fight line nioveinent'in the sleeve; Thevalve 28 may have a reduced passage 29 tlierecln'ouglg, lo nil-eventcompressionbe tween lie id the cop The valve i' u see SO mount-ell to18. 1 fi-lie ciirrier 1%.

A;compres- 813G131 30', the lower end of the spring engaging the abutment34;, and the upper end of the en uging (he base 18 of the car" rier ll.

Each of the cylinders 2 is provided with two valve sfrucifiurcs of thesort above mentioned. Preferably noting; Fig. l, the valves oi theinnermost stems 30 are intake valves the valves of the outermost stemsbeing exhaust valves. The novelty, however, resides in the. specificvalve construction, whethe" or not the some be duplicated, and whetheror not. the consirnclion relates to I iini elce valve or an exhaustvalve.

The operation of the valves 28 is simple, lVhen the 03111 shaft 4i isroizuzod, the coin 5 raises and lowers the plunger 5nd the letter andlowers the stern 30? when the stem 36 is raised, the spring ofi willbepurunder compression, and the stem 30 will move downwardly under theaction of the sion spring 36 surrounds a portion of each sleeves 22, thevalves 28 and. the stems 30.

in this way, access is had to the space in the cylinders 2 above thepistons 7 and any of the valves 22 may be taken out of the block orcarrier 14;, readily, by moving the cap,

The valves 2% are lubricated by means of the oil cups 2'2. It is to beobserved that carbon deposits on thewvalves 28 will be scraped off to alarge extent, as the valves reciprocate, and since che valves are not ofthe common bevel-edge type, carbon cleposits cannot accumulate betweenthe valvesand their seats, thereby preventing a proper closing of thevalves.

Having thus described the invention, what is claimed is:-

An internal combustion engine comprising' c cylinder having" a lateralshoulder; a. carrier having a, bore and a single pair of oppositelydisposed ports located at the some elevation, one of which ports opens;into the cylinder, the other of which ports opens directly lhrongh theouter wall of the carrier, the carrierbeing supported on the shoulder;means for securing the carrier detacllubly to the cylinder; a sleeve ofcommon diameter from end to end seated in the bore and having portscoinciding-With the ports of thecairrierya solid disk-like valve mountedto reciprocate in the sleeve and of sufficient thickness to, close theports, the

valve having e minute opening therethrough; a closure threaded into thecarrier and engagingthe sleeve to hold the same in the bore; and alubricating means mounted directly on the closureand discharging intothe sleeve, the closure being imperforate about the lubricating means. y

In testimony that lclaim the foregoing 'asmy own, I have hereto effixedmy signer ture in the presence of two Witnesses.
